特朗普入主白宫以来，美国在应对气候变化领域出现一系列倒退做法。在2018财年预算中，美国联邦政府在气候变化活动方面的投入出现“断崖式”下降，几近全面停止。奥巴马政府时期，美国提供的国际气候资金总额位居全球前列。2009年至2016年，美国提供气候资金的总体趋势为：气候资金规模增加；资金来源市场化趋势增强；资金流向在亚、非、拉三洲基本持平；重点投资领域是温室气体减排特别是清洁能源开发。特朗普政府停止向国际气候变化项目出资会带来三个直接后果：一是加大国际气候资金缺口，二是削弱《巴黎协定》缔约国履约能力，三是对适应气候变化行动产生负面影响。预计特朗普政府未来仍将“断供”国际气候资金，但是，部分资金缺口有望得到弥补。
Since Trump took the office，the United States has seen a cluster of fallback in combating climate change. In the fiscal year 2018，the U.S. federal government's investment budget for climate change activities took a tumble. During Obama administration，the total amount of international climate finance provided by the U.S. was among the highest in the world. From 2009 to 2016，the overall trend of climate fund provided by the U.S. consists of the increase of climate fund and marketization of fund raising，the financial balancing among Asia，Africa and Latin America，and prioritization of clean energy development aiming at greenhouse gases reduction. Trump's suspension of the international climate fund produced three immediate consequences，increasing the supply-demand gap of international climate fund，weakening the compliance prospect of parties to the Paris Agreement，and affecting the adaptation activities to climate change. For the near future，there would be faint hope that Trump restart international climate fund，and the gap of which could only be filled otherwise.
